Pull Request Overview
This PR migrates the CurrentBlockWatcher's transport from web3 to alloy, introducing an unbuffered transport implementation to avoid latency issues on high-frequency chains. The migration maintains parallel batch execution while leveraging alloy's default behavior of fetching blocks without transaction details.
Key Changes:
- Introduces
unbuffered_provider()in alloy module to avoid batching delays - Migrates block fetching logic from web3's batched RPC calls to alloy's
get_block()with parallel futures - Updates
BlockInfoconversion to work with alloy's block types instead of web3

Description
Migrates the CurrentBlockWatcher's transport to alloy.
Changes
How to test
Existing tests + mainnet shadow.
Further implementation
It should be safe to migrate to WS using alloy's WsConnect, which implements a reconnection logic internally. That should reduce the RPC load.
